JOHN R. PIERCE, OF ASTILE, NEW YORK.

NECK-YOKE.

Specificatoniof Letters Patent No. 10,991, dated May 30, 1854.

To all 'whom may conern Be it-known that I,` JOHN R. PmRcn, of Castile, in the county of Wyoming and State of New York, have invented a new and useful Improvement in Neck-Yokes for Horses and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the anneXed drawings, forming part of this specification, in whichi Figure l is a side view of the yoke. Fig. 2 is a longitudinal section perpendicular to the axis of the bolt Z). Fig. 3 is a view of the under part of the yoke.

Similar letters of reference denote the same part.

The object of my invention is to furnish points for the attachment of the breast straps, which shall be movable longitudinally on the yoke, to accommodate the side movement of one or both horses; the attachments being so connected that the movement of one will produce a similar movement of equal eXtent in the other, thereby causing the attachments to continue at all times atequal distances on each side of the carriage ole.

p The invention consists in forming the yoke with a cavity sufiiciently large to contain-the movable parts, namely, two racks and a pinion upon the main bolt, the racks carrying the attaching bolts, and being otherwise arranged as will be hereafter set forth.

To enable others skilled in the art to make and use my invention I will proceed to describe its construction and operation.

-In the drawing a is the main ring, held by the bolt b, on which is the small pinion c moving loosely upon it. The attaching rings (Z and e are held by the eyes f on the racks L h', which racks mesh into the opposite sides of the pinion o; the eyes f pass through slots in the top of the yoke, while the racks are kept in position by the plates `z' secured to the racks by pins p which move in the slots Z on the under side of the yoke. The lower side of the yoke has a metal face m which being screwed to the wooden shell as shown in the drawing, strengthens the yoke and secures the racks.

The operation of my improved yoke is as follows: The horses being attached to the yoke in the usual manner, and driven for- Ward, any movement of one of the attaching rings, revolves the pinion c, causing the rack carrying the other ring to movelongitudinally in the same distance in the opposite direction, thus enabling the horses to move either from or toward each other without deranging the position of the pole; the attaching rings being by this arrangement always at equal distances from the main bolt.

What I claim as my invention and desire to secure by Letters Patent, is

Placing the attaching rings of neck yokes uponl'racks passing on each side'o'f a pinion movable upon the main bolt, or any arrangement substantially' the same, for admitting of the equal longitudinal movement of the said rings as, and for the purposes herein set forth.

In testimony whereof, I have hereinto signed my name before two subscribing witnesses.
